Hi! I''m trying to develop a web chat (like the facebook one, but much simpler) that works inside Rails 3, and so I''m inquiring about the methods used for this scope. I had some success applying this guide http://www.web2media.net/laktek/2010/02/16/building-real-time-web-apps-with-rails3/ , so now I am able to send messages form the server to the client. Anyway, I read about some sort of XML-based protocol called XMPP, which seems to be widley used in this cases. I really don''t know anything about either cramp...
